Abstract: A magenta toner for developing electrostatic images provided which contains a binder resin and a colorant, wherein the colorant includes a mixed crystal of two or more colorants and when a solid patch is fixed on art paper complying with the ISO standard by using this toner, a resulting fixed image color satisfies at least one of the following formulae (b*)<0.85 (a*)?67.92; and (b*)>?7.94(a*)+591.85. The color difference ?E between the color of the fixed image and the color characterized by L*: 46.6, a*: 75.1 and b*: ?4.4 is preferably less than 6. The colorant is preferably a mixed crystal of a quinacridone colorant and a monoazo colorant. Moreover, the invention provides a method for producing the magenta toner, a developer containing the magenta toner, and an image-forming method using the magenta toner.

Abstract: The present invention provides an image forming method comprising the steps of forming an electrostatic latent image on a surface of an electrostatic latent image bearing body, forming a toner image by developing the electrostatic latent image by using a toner, transferring the toner image to the surface of a recording medium, and fusing the transferred toner image on the surface of the recording medium by bringing the toner image into contact with a heating medium, which has a resin coating layer formed on the surface thereof, and thereby melting the toner image. The toner contains a binder resin containing monomers having vinyl double bonds. A storage elasticity of the toner at 180° C. is in a range of 1×103 to 8×103 Pa and a contact angle of the surface of the heating medium to water at 25° C. is in a range of 50 to 100°.
